Prepaid
The billing method for the main package and additional purchase items of the CFW is Prepaid.
Type | Details |
Overview | Tencent CFW provides three paid editions for users: Premium Edition, Enterprise Edition, and Ultimate Edition. These three editions use a prepaid (monthly subscription) mode: Users pay a one-time fee for one month, several months, or years based on their needs. After successful payment, the relevant resources of Tencent CFW will be allocated to the users by the system. If the user does not renew upon expiration, these resources will be reclaimed. |
Advantage | For long-term protection, the unit price is lower than pay-as-you-go. Long-term locking of cloud resources to avoid situations where no cloud resources are available. |
Applicable Scenario | When users exhibit the following characteristics, it is recommended to use the prepaid mode. Have relatively stable business scenarios. Need to use cloud resources for a long time. |
Postpaid
The following CFW features support specification expansion in a pay-as-you-go format:
Feature | Description | Price |
Log Analysis | Pay-as-you-go charges you based on the actual storage usage, which is suitable for users who need uninterrupted storage of logs but cannot estimate the log volume growth. | 1000 GB to 6120 GB: 0.006 USD/GB/day Above 6120 GB: 0.004 USD/GB/day |
NAT Firewall | Elastic protection is activated when traffic exceeds instance specifications in the pay-as-you-go billing mode, providing the ability to handle temporary peak traffic. | 2.41 USD/Mbps/day |
Inter-VPC Firewall | Elastic protection is activated when traffic exceeds instance specifications in the pay-as-you-go billing mode, providing the ability to handle temporary peak traffic. | 0.09 USD/Mbps/day |
Billing Instances
Suppose you enable elastic protection for the NAT Firewall at 12:00 on a certain day. The traffic of the NAT Firewall instance reaches 550 MB, and the instance bandwidth specification is 500 MB. The elastic cost for that day would be (550-500) x 2.41 x (24 - 12) / 24 = 60.25 USD.
Suppose you enable pay-as-you-go storage for log analysis at 00:00 on a certain day. Your log storage specification is 1500 GB, and 36 GB of new logs are generated that day. The cost for the day would be 1536 x 0.006 = 9.216 USD.
Suppose you enable elastic protection for the Inter-VPC Firewall at 06:00 on a certain day. The traffic of that Inter-VPC Firewall instance reaches 1000 MB, and the instance bandwidth specification is 800 MB. The elastic cost for that day would be (1000-800) x 0.09 x (24 - 6) / 24 = 13.5 USD.
Billing Process
1. Recharge first to ensure the account balance is greater than the pre-frozen amount. After recharging, you can normally activate the pay-as-you-go service.
2. After selecting and purchasing a pay-as-you-go product, the system will start pay-as-you-go based on usage. Common settlement cycles include hours, days, and months.
3. Once it is activated, the system will freeze an estimated amount based on the product's settlement cycle and historical usage.
4. On the settlement date, the system will thaw the frozen amount for the device, release it to the available balance, and then proceed with settlement.
5. When the settlement cycle is reached, the system will rate and deduct fees based on usage and unit price, and generate a bill .
6. In case of overdue payment, the NAT Firewall and Inter-VPC Firewall elastic features will be disabled. If your CFW main package is within the validity period, the NAT Firewall and Inter-VPC Firewall will continue to provide protection based on instance specifications.
